  • Have you heard of the USMLE Step 3? It’s a 16 hour exam covered over 2 continuous days, with 550 multiple choice questions and 12 simulated 20 minute cases. You should really read about this exam. The questions are a page length to be finished in less than a minute, the exam spans all clinical fields across medicine, all medicine subspecialties, pediatrics, obs/gyn, biostatisitics, general surgery.

    GRE et all are a piece of cake really..

    • Well said Harsh.. the first round includes 336 mcq and 2nd one has 114 mcq. But consider the cutoff scores and competition also. In gre you have to score at least 336-340 out of 340 to get admission in top universities in the world which is definitely not a piece of cake.

  • This is absolutely wrong as aipmt is,according to me,the toughest exam on this planet and in this it is not even mentioned.Strange!!you know what,only 70 seats are there in AIIMS delhi ,out of which 50% is reserved.Approx. 1 lakh students give this exam.So,don’t you think it is d toughest?

    • Varun Kumar says:

      Hello Priya!
      Well, it’s a national level exam and you have mentioned the seat matrix of Delhi only. Moreover, the toughness level of AIPMT is quite lighter than AIEEE. I would also like to tell you that there is a huge difference between competitive exam and tough exam.
      Thanks for sharing your thought with us 🙂

      • Hemant Bhardwaj says:

        that’s national level exam with national statistics!

    • Mohan Kumar says:

      All Souls Prize Fellowship Exam. 2 Candidates selected per year. Even the entire world writes the exam only 2 candidates get the fellowship. Where are our f**** brain goes. If we are in India it doesn’t means Exams in India are the toughest. Idiots at their best.
      Master Sommelier Diploma Examination. Can u fu**** smell 6 wines and say what type of grape variety used and from which country with region and which year it is made without opening your eyes. It will take Infinite years for us to find them.

    • Harsh Der says:

      Not at all even many state level exams are tougher than that.

  • sorry,1.5 million people write jee main 150000 qualify for jee advanced and out of that 10000 people clear iit,acceptance rate 10000/1500000 equals 0.67% it is not over yet if you belong to general category then only 4000 seats are allocated for you(caste reservation system)and you must get below 3000 to get a decent group from a decent iit.iit bombay computer science has only 50 seats and all 1.5 million aim for that..the difficulty of paper is equivalent to that of international olympiads if you feel they are easy then you are wrong,when you write olympiad you will be writing it in one subject that too your favorite,but for jee you will be writing it in 3 subjects(phy,chem,mat) that too at the same time.people whose ranks are below 50 would have been dfeinitely successful,and mostly Top 10 rankers would possess a medal from international olympiad and top 5 would possess a gold medal.

  • U guys should try writing CA finals

  • Dharmanshu says:

    The toughest is IAS , not IES and IIT is tougher than CAT and GATE….
    Which noob made this list? Probably some humanities-studying dumbass.
    15 lakh aspirants appear for IIT and 1.5 qualify the first round , after which tere is the second round which is much tougher than the previous one , and only 10,000 get selected. Now you may think that your job is done , but no. If you belong to general category , you only have 5000 or less seats. The rest are reserved for SCs , STs , OBCs and PWDs. Try qualifiying that

    • Hemant Bhardwaj says:

      it’s 12 lakhs not 15 lakhs in iit, with 10,000 selection the selection ratio is around 1:120. in civil services, total number of candidates=5 lakh, total selections around 400(IAS,IPS,IFS, etc), selection ratio 1:1000. in IES(Indian engineering services) selection ratio is around 1:500.

    • Mohan Kumar says:

      Whatever happens 1000+ are selected each year. You are the most dumbest person in the world.
      All Souls Prize Fellowship Exam –> only 2 person in the entire world is selected per year. you Idiot of Idiotic idiot. 200 in 40 year history. Do u think only 200 IAS were during this period.
      Master Sommelier Diploma Examination –> Can you fu*** taste a wine with your eyes closed and find the type of grape used (there are 10000+ wine grape varieties in the world) and tell where it is from which country and that too which part (e.g.Daulatabad grape) and also the year the wine is made (how will you find the taste difference of 1778 wine in spain and 1994 wine in switzerland) just by tasting. Fu**** we Indians just need to read some pretty easy books compared to these exams. IAS may be tough but each year there are 1000+ IAS but in the entire world there are 227 Sommelier who take the exam Master Sommelier Diploma Examination. There are only some 200 cleared All Souls Prize Fellowship Exam.First know about all the above exams before giving your answers. You are proving how an Indain mind will be as like “India is best. Indian exams are tough. india team is best.” Your comments makes no sense.

    • Syed saim says:

      Huh! You fool… Don’t you know the difference between competitive and Toughest exams…IIT is the most competitive exam and applicants are huge in numbers and available seats are low. Whereas CA is the toughest academic exam in india coz the difficulty level of questions will drool you. Haven’t you heard a dialogue in india that the guy keep attempting CA every year but couldn’t and there comes a point of time when the guy is still attempting CA while the girl who used to study with her is mother of Three. Anyways nothing is this world is impossible!

    Have taken GRE and CA exams. CA is definitely not the toughest. CA should not even be on the list. The exam and the subject matter in CA exams are not tough at all – the grading is tough because it is quite arbitrary. If they conducted Indian CA exams in the computerized multiple question format like CA exams in the U.S. (or like 99% of other professional exams in India and around the world) one will realize this. Moreover, Indian CA exams involve a lot of ‘mugging’ (rote memorization) and the exams questions require very little application of the subject matter. GRE being one of the toughest is also a joke. I studied for the exam for one week and did pretty well. The math is basic high school math and the verbal section is not that hard either (personally I found verbal super easy). However, GRE at least is application based and does not require mugging (except the vocabulary part to some extent). The professional exams in medicine and law are probably the toughest. USMLE is most likely one of the toughest (if not the toughest) exam on the planet – the sheer volume of subject matter and the exam itself (3 levels, two day 7-9 hour long exams with minimal break time) – is pretty insane. My older sibling took the USMLE and I know for a fact that including professional exams in medicine/law with Indian CA exam and GRE is an absolute joke. No offense, but people who write these blog posts really should do some research. It is clear from the article and the writer’s bio that the writer doesn’t know what he’s talking about. Also, in my humble opinion I find professional exams in the U.S. much tougher because the questions are tricky and require test takers to think and apply what they have learnt (not just blind mugging), something many Indian exams like CA lack (I can only speak for CA – perhaps this is not the case with other fields like engineering etc.)

    • Nwachinemelu says:

      I agree with you absolutely! As a practicing physician in the US, I strongly believe that the USMLE step 3 is the toughest exam in the whole world by far. Exam that not only tests your medical knowledge, skills, and applications on complex medical and surgical cases and procedures, the exam tests your brain’s endurance (2 continuous days exam each 8 hours with 1 hour break the whole day). And each question is 1-11/2 pages requiring you to scroll down the computer screen to access the remaining parts of the questions and you only have less than a minute to answer each question total of about 550 questions in 2 days. Exam tests all you have learned from pre med, medical school, internship, and residency years and scores are very competitive. The good thing is that once you pass the step 3 exam in less than 4 attempts, you will be licensed to practice medicine in most states in the United States. That’s insane!
